Matrix Code Tutorial Help Needed - Symbols wont change

Question

Please could someone help me out with this Flash problem, I would really appreciate it.
I have followed the guide at this link to create a matrix code effect. The matrix code font file is available to download from this site also (mCode15).
Once I get this file up and running and understand how it works, I'm going to tweak it somewhat to suit my needs.
I  am, however, experiencing some problems getting it to work as described  in the tutorial. I have followed the tutorial to the letter, but when  the flash movie file runs, only the glyph symbol that I used to create the_one and one_pod movie symbols is displayed in the code that scrolls  down screen. I have embedded the font the way it describes and even  added it to the library and set it to export for actionscript using the  linkage option. But the matrix code that rains down is still only one  symbol which never changes.
Please please help me out with  this as I'm slowly losing my sanity trying to figure it out. I am using  Flash CS3 on a Windows 7 PC to do this and the file is set up up as action script  2.0.
Many thanks for any help you can provide.
The Action Script code from the site is included below, this is pasted into the 1st frame.

When you dynamically add content, it has no home on the timeline unless you anchor it in one.  If you were to manually place an empty movieclip on the timeline in the lowest layer and then and then create the matrix stuff in there then you would have it living in the background.
Try creating such a movieclip, located in the upper left corner of the stage and assign it an instance name of "theMatrix"
Then remove the following lines from your existing code (which is otherwise creating that mc dynamically)...
// Create an empty Movieclip to hold the Matrix.theMatrix = createEmptyMovieClip('MatrixCode',1);
That should be all you need to do.
